Formula explanation

How this calculator works

Core formula

project pregnancy, fertility, or family-planning dates from the anchor date and cycle assumptions provided

The calculator uses standard obstetric timing rules for due dates and fertility windows, plus simple date math for baby age and leave planning, so you can move from one known milestone to the next.

Cycle-based fertility estimates are planning tools and not guarantees of ovulation timing.
Medical due dates and pregnancy progress should always be confirmed with a clinician when accuracy matters.
